Office: SL 260-A; Phone: 274-6038 or 581-8816;
Class Hours: M: 4:00 – 5:15 pm, SL 165
W: 4:00 – 5:15 pm, SL 050
Prerequisites: ME 262 and ME 272
Textbook: S. Moaveni, Finite Element Analysis – Theory and Application with ANSYS, Prentice Hall, New Jersey, Second Edition, 2003.
Description: Introduction to the use of finite element methods for analysis and design. Applications involving stress analysis and heat transfer of solids. The use of existing software and hardware for computer-aided engineering.
Course Outcomes: After completion of the course, the students will be able to:
Derive and manually solve finite element problems consisting of one-dimensional structural elements
Use the finite element method for stress analysis and design of structures in multi-dimensions
Use the finite element method for heat transfer analysis of solids in multi-dimensions
Use commercial finite element codes competently for most analysis and design problems
Create geometry and models for 2D and 3D complex systems
Make checks to verify and evaluate the accuracy of finite element solutions
Write good project reports describing and evaluating the obtained results
Give good oral presentations of projects
Organization: Homework problems and a final project will be assigned during the semester for analysis and design of mechanical parts. Ansys, which is a commercial finite element program designed for solution of multiphysics problems, will be used throughout the course. Emphasis will be on stress analysis and heat transfer of solids.
Topics: 1) Finite element formulation via direct methods
2) Finite element formulation via minimum potential energy principle
3) Stress analysis – bars, trusses; beams, frames; plates, shells, and 2D/3D solids
4) Heat transfer analysis of solids – bars and 2D/3D solids
5) Dynamic problems
6) Applications using Ansys
Tests (2) 40% (20% each)
HW & Lab Assignments 40%
Final Project 20%
2. REQUIREMENTS FOR HOMEWORK ASSIGNMENTS
Homework assignments and final project constitute an important part of this course. Each assignment requires the use of a computer program to solve a design related engineering problem. In addition to your performance in the tests, you are required to demonstrate your technical ability through the way you present solutions to the problems. Your assignments will be graded based on the correctness as well as the neatness and organization of the presented material. The following is a list of the minimum requirements:
• Late assignments will be accepted, but there will be a penalty of five percent for each late day.
• All work must be done individually unless group projects are assigned.
• All computer outputs and graphics must be submitted in an 8.5 in by 11.0 in size format.
• For all assignments, the problems solved must be documented adequately.
The final project report must include the following sections with headings and the numbering as shown:
Title Page – Project Title, Course Name, Semester, Student (s) Name, Professor Name, Date, etc.
1. Summary – List objectives and describe concisely the work accomplished (one or two paragraphs).
2. Introduction – Briefly describe the project background and related previous work.
3. Theoretical Background – In terms of equations, figures and technical description.
4. Model Details – Including boundary conditions, meshes used, loads applied, etc.
5. Results and Discussions – Including plots and tables of important results.
Appendix – including extra printouts and plots of secondary importance
1) During the second half of the semester, the instructor will give a grade of "W" only if the student has a passing grade in the course at the time of the withdrawal request.
2) Students should not enroll in the course unless they have met the prerequisite requirements.
3) Previous offerings of the course showed that attendance in the lectures and preparing for the lectures in advance by following the reading assignment are essential for success in the course. The students are urged to come to class regularly in order to receive good grades.
4. Information on Accessing ANSYS
You will need an access to the Ansys computer program for some of the homework problems to be assigned. Access to Ansys is possible through the following means:
Using the Windows/NT computers of the Computer Network Center (CNC) of the School of Engineering and Technology located in ET105. This will provide an access to the educational version of Ansys (ANSYS/ED) which has a restriction on the number of elements to be used. A CNC/NT account is required in order to access MATLAB in this cluster. See the CNC homepage at http://www.engr.iupui.edu/iupui/cnc for information to obtain a CNC account.
Using a program called Citrix via Internet on the site: http://cpt-citrixweb.sl.iupui.edu. This is the same educational version as on the CNC network. An Internet Browser program – such as Internet Explorer and Netscape – is needed to access Ansys using your IUPUI username and password. If you are using the Citrix for the first time on your computer, you need to load the Citrix Client program, ICA, which will allow you to use it. Instructions on how to install this program are available, when you connect to the Citrix site.
Connecting to the ME/UNIX computer mesolv via telnet (mesolv.cadcam.iupui.edu) from a remote terminal and executing the command ansys61. This is a commercial version which does not have any restriction on the number of elements to be used. A CNC/UNIX account is required on the mesolv server and an X-terminal or an X-terminal emulator on a PC.
Using your own student version of Ansys, which may be ordered from Prentice Hall.
More details will be provided during the semester.
5. ONLINE SUPPORT
Online support is provided for this course via the Oncourse system at IUPUI. The following information will be available for students throughout the semester on the World-Wide-Web:
Detailed course schedule
Solution of homework problems
Access to ME 450 Web site is available via Oncourse at http://oncourse.iu.edu/. The students are expected to check the ME 450 page regularly for the above information, announcements, schedule changes, etc.
